A highly biodegradable inorganic fiber fireproof molded article which exhibits desired heat resistance even without containing ceramic fibers such as alumina silicate fibers, alumina powder and silica powder, and at the same time reduces manufacturing cost and product cost. 2 to 95% by mass of biodegradable inorganic fibers having a solubility in physiological saline solution of at least 1% by mass at 40 캜, 2 to 95% by mass of an inorganic powder having a needle-shaped crystal structure and 3 to 32% by mass of a binder Wherein the average length of the inorganic powder having a needle-shaped crystal structure is 1 to 3000 μm and the aspect ratio is 1 to 1000. |
